Portable animal tether device
Abstract
An animal restraint and/or tethering device is composed of a metal rod with
one end being pointed to allow easy insertion into the ground, and the
other end having a flat metal disk affixed transversely to it. The rod
also has one conventional nut affixed around the rod slightly below the
disk. Both the disk and the nut are welded in place. The device has two
metal chain-like links, one encircling the metal rod below the disk and
above the nut, and the other interlinked to the first link but not
encircling the rod. Both links are loose so as to rotate freely around the
rod. This allows any standard lead or leash loop handle to be received
through the loose link and looped over the disk and around the rod and be
held in place by the disk and link members.

Claims
I claim:
1. An animal tethering stake comprising:
an elongated shaft adapted for insertion into the ground;
a retention member secured to and extending radially outwardly about an
upper end of the shaft;
a stop element secured to the shaft below the retention member and spaced
therefrom, the stop element serving to limit penetration of the shaft into
the ground;
a first elongated link rotatably disposed about the shaft between the
retention member and the stop element; and
a second elongated link interlinked through the first link and receiving a
hand loop of a leash therethrough;
whereby, the hand loop extends through the second link, holding the second
link in an upright position above the first link, and is looped over and
around the shaft and retained thereon by the retention member, thus
drawing the hand loop tight against the shaft, the hand loop being free to
rotate about the shaft in conjunction with the first and second links.
2. An animal tethering stake according to claim 1, wherein: the retention
member and the stop element are secured to the shaft as by welding.
3. A tethering stake according to claim 1, wherein the shaft has a pointed
lower end portion for insertion into the ground.
4. An animal tethering stake according to claim 3, wherein: the retention
member and the stop element are secured to the shaft as by welding.
5. A tethering stake according to claim 3, wherein said retention member
comprises a disk.
6. A tethering stake according to claim 1, wherein said retention member
comprises a disk.
7. A tethering stake according to claim 1, wherein said stop element
comprises a nut secured about the shaft.
Description
BACKGROUND OF THE INVENTION
This invention relates to a device for the temporary tethering and/or
restraint of dogs or other such animals.
The prior art is predominantly composed of stakes which require a tool such
as a hammer for striking the device or a wrench for turning the device to
complete installation for use. Furthermore, removal may also require a
wrench or digging tool to achieve separation of the device from its
emplacement. The necessity of such tools reduce the ease of transfer and
portability of those devices. The prior art also requires that some
assimilate of clasp, clip or hook be used once the device has been
implanted to attain the connection of the tether line. Otherwise, some
means of knot must be tied to complete the tethering. Also, many of the
prior art stakes have exposed members which may, by design, expose man and
beast to potential harm by puncture from, or tripping over, the device.
BRIEF SUMMARY OF THE INVENTION
The instant invention is comprised of a metal shaft with a flat metal disk
at the upper end of the shaft, a standard nut around the shaft slightly
below the disk, and a point at the lower end. One elongated metal link
encircles the shaft below the flat disk, and above the nut. A second
similar link is interlinked into and around the first link, but not the
shaft.
One principal object of my design is to allow quick insertion and removal
for temporary use in any grass, dirt or hard packed sand area, without the
need of tools for driving or turning the device. However, in extremely
hard areas, a mallet or hammer may be used to drive the shaft into the
ground without fear of damage to the device. The device is also designed
to be easily removed from the ground and repositioned for use from place
to place and thus is readily movable or portable.
Another principal object of my design is for the device to receive the loop
handle of any standard lead or leash through the second link member and
then be looped over the disk and around the shaft, such that the loop is
held in place by the disk and link members, therefore eliminating the need
of any extra clasps, clips, hooks or knots.
Furthermore, the device is durable in that it has no internal elements or
bearing parts to break or malfunction under pressure of normal insertion,
removal or use, and it has a minimal lifetime wear.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 shows a front, side or cross view of the invention.
FIG. 2 shows a top view of the invention.
DETAILED DESCRIPTION
Referring to the drawings, the numeral 1 indicates a cylindrical metal
shaft, rod or stake which is the main body of the device, and is used to
penetrate the ground in which the device is used. In FIG. 1, the bottom
end 2 is pointed similar to the tip of a nail so as to facilitate
penetration of the ground. The top end of the shaft 1 has a flat metal
disk 3, larger in diameter than the shaft 1, affixed transversely thereto
by means of welding. Below the disk 3, slightly down the shaft 1 and
encircling the shaft 1, is a standard nut 4 also affixed to the shaft 1 by
means of welding. Encircling the shaft 1 below the flat disk 3 and above
the standard nut 4 is one elongated link 5 with a second similar elongated
link 6 interlinked through the first link 5, but not around the shaft 1.
This then allows both links 5-6 to rotate freely around the shaft 1.
Insertion of the shaft 1 into the ground is achieved by placing the heel of
one's hand on the top of the disk 3 and applying pressure downward while
at the same time applying a twisting motion clockwise and counterclockwise
until the shaft 1 is sunken into the ground up to the underside of the nut
or stop element 4.
Removal of the device is obtained by grasping the top disk 3 and pulling
upward while twisting the device in a manner similar to that used for
inserting the shaft. If the device cannot be twisted by hand, one should
place a correctly sized wrench on the nut 4 affixed to the shaft 1 and
rotate the shaft 1 to break the bond with the ground. Then the top disk 3
is grasped and pulled upward out of the ground.
The device is designed to allow the use of any standard leash 7 by
inserting the hand loop 8 of the leash 7 through the loose elongated link
6 while holding this link 6 in an upright position above the link 5 which
encircles the shaft, and then looping the hand loop 8 around the shaft 1
below the disk 3 and drawing the leash 7 back to bring the hand loop 8
tight against the shaft 1. This then eliminates the need of any extra
clasps, clips, hooks or knots. If the device has been inserted into the
ground up to a depth where the nut 4 is in contact with the ground, this
will then allow any lateral pressure exerted by the leash 7 to be
transferred to the shaft 1 and allow free rotation of the leash 7 around
the shaft 1 without potential entanglement with the device.
